Jet-powered snow plow once deployed on B.C. highways
Powerful truck was fitted with a Pratt and Whitney ST6A turbine turboprop engine.
It might sound like a harebrained Homer Simpson creation, but a jet-powered snow plow once existed and was temporarily put to work on B.C. highways.
According to a bit of local highways maintenance history, recently re-shared by the B.C. Ministry of Transportation and Infrastructure on its Facebook page, in the early 1960s, the province experimentally fitted a 285-lb ST6A turbine turboprop engine, manufactured by Pratt and Whitney Canada, into a snow plow. The result was a 31,100-lb (unloaded) truck that ran on diesel (but could also run on furnace oil and gasoline), and put out 320 horsepower.
By comparison, the typical truck used weighed 2,000 lbs and put out 250 horsepower.
